Show HN: Web viewer for gene measurements (single data file and OpenSeadragon)

To try it out, click the button "open some example data files and layouts".

About the software design:

All pyramidal photo tiles and gene expression measurement data are combined into one single file.

Instead of downloading the whole experiment data file, the viewer makes use of HTTP Range requests to first download an index and then only fetch the relevant parts of the file. The viewer can also be used offline for viewing locally stored experiment data files.

To avoid flickering while zooming in and out, the measurement points were painted on the photo tiles instead of making use of an overlay. The software is open source and availalbe on GitHub
